Abstract

PROBLEM TO BE SOLVED: To securely mount at a correct position, an air filter for covering from a lower portion a cooling air intake hole formed in a lower surface of an ice making machine. SOLUTION: This air filter 14 is inserted from a front portion into a rail 12 mounted on a lower surface of an ice making machine body 10 to cover from a lower portion a cooling air intake hole formed in the lower surface of the ice making machine body 10. A knob part 17 is formed on a knob 16 of the air filter 14, on a front end of which an upward protrusion 18 is provided. The protrusion 18 abuts against a front surface lower end part 19 of the ice making machine body 10, and is constituted so as to interfere with a lower end of a door in the ice making machine when it is not correctly mounted on the rail 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice making machine, a refrigerator,
The present invention relates to an air filter for covering a cooling air intake port formed on a lower surface of a main body of a storage or the like from below, and particularly to an installation mechanism thereof.

[0002]

2. Description of the Related Art As shown in FIGS. 6 to 8, in a conventional automatic ice making machine 1, an intake port (not shown) for cooling air is formed between legs 2 on the lower surface of the ice making machine. 1
Cooling air is taken in as shown by the arrow and the ice machine 1
On the other hand, the air filter 4 is inserted from the front to the rails 3 attached to the lower surface of the ice making machine 1 with the intake port sandwiched therebetween, and the air filter 4 causes the intake port to be discharged. 9 is covered from below, but if the air filter 4 is not sufficiently inserted into the rail 3 as shown in FIG. Dust is sucked into the inside of the ice maker 1 and insects and the like are easily infiltrated therein. As a result, not only is the inside of the ice maker 1 contaminated and unsanitary, but dust and carcasses of insects are accumulated in the ice maker 1. Ventilation is impaired, and the basic performance of the ice making machine 1 may be impaired.

An instruction label is usually attached to the ice making machine 1 so that the air filter 4 can be fully inserted into the rail 3. However, the instruction label may be peeled off or the characters of the instruction label may be removed for some reason. There is a danger that the air filter 4 will not be fully inserted, and the air filter 4 is inserted on the lower surface of the ice making machine 1, and the insertion state of the air filter 4 is very difficult to understand. In addition, it is difficult to notice the insufficient insertion of the air filter 4, and in these cases, the above problem occurs.

[0004]

SUMMARY OF THE INVENTION According to the present invention, an air filter, which is formed on the lower surface of the body of an ice making machine, a refrigerator, a storage, or the like and covers the intake of cooling air from below, is securely attached to a regular position. Is what you are trying to do.

[0005]

Therefore, an air filter device for an ice making machine or the like according to the present invention is mounted on a rail attached to the bottom surface of the body of the ice making machine or the like, and is used for cooling air formed on the bottom surface of the body. There is an air filter that covers the intake port from below, and the end portion of the air filter extends upward and interferes with the lower end portion of the door in the ice making machine or the like and is pushed to the lower end portion of the door by closing the door. A protrusion that abuts the lower end surface of the main body.

Therefore, even if the air filter is not properly mounted on the rail attached to the lower surface of the main body of the ice making machine or the like, the upward protrusion of the end portion of the air filter is pushed to the lower end portion of the door by closing the door. By contacting the lower end surface of the main body, the air filter is securely attached to the regular position on the lower surface of the main body, so that the intake port for cooling air formed on the lower surface of the main body is completely covered from below by the air filter. Will be able to.

[0007]

Embodiments of the present invention will be described below. 1 to 4, the automatic ice maker main body 10
An unillustrated intake port for cooling air is formed between the leg portions 11 at the rear of the lower surface of the rail, and rails 12 are attached to the lower surface of the ice making machine body 10 so as to face each other with screws 13 sandwiching the intake port. An air filter 14 is inserted into the rail 12 from the front, and the intake portion is covered from below by the filter portion 15 of the air filter 14.

A handle 1 is provided on the front portion of the air filter 14.
6 is provided, and the air filter 14 is
The handle 16 can be freely displaced back and forth along the rails 12, and the front end portion of the handle 16 is provided with an upward projecting portion 18, and the projecting portion 18 serves as the projecting portion 18. By contacting the lower end portion 19 of the front surface of the air filter 14, the air filter 14 is sufficiently inserted into the rail 12 to the regular position, and the filter portion 15 completely covers the intake port from below. The protrusion 18 is configured to interfere with the lower end of the door 20 of the ice making machine body 10. In addition, 21 is a door packing.

Therefore, as shown in FIG.
Even if the air filter 14 is not fully inserted into the rail 12, if the door 20 is closed as shown by the arrow,
As the lower end of the door 20 interferes with the protrusion 18, the air filter 14 is pushed rearward, and the protrusion 18 is brought into contact with the lower end 19 of the front surface of the ice making machine body 10. As a result, the air filter 14 automatically moves to the position shown in FIG. And it will be mounted in the regular position shown in FIG.

As described above, since the air filter 14 is of the front drawer type of the ice making machine main body 10, opening and closing the door 20 allows the air filter 14 to be taken in and out along the rail 12, and the air filter 14 The handle portion 17 provided on the handle 16 makes the above-mentioned taking-in / out operation extremely easy, and the upward projection 18 provided on the front end portion of the handle 16 is brought into contact with the lower end portion 19 of the front surface of the ice making machine body 10. As a result, the air filter 14 is sufficiently inserted into the rail 12 to the regular position, and it is not necessary to separately provide a stopper or the like for determining the regular position of the air filter 14, so that the cost can be easily reduced. .

Further, even if the air filter 14 is not sufficiently attached to the ice machine body 10, the air filter 14 is automatically attached to its regular position when the door 20 is closed. The inlet of the cooling air in 10 is always completely covered from below by the filter portion 15 of the air filter 14, so that dust, insects and the like are sucked into or intruded into the ice making machine body 10 from the inlet. Is reliably prevented, and the inside of the ice making machine main body 10 can be kept hygienic at all times, and at the same time, the basic performance of the ice making machine can be exhibited for a long time without change.

The present invention is not limited to an ice making machine, but a refrigerator,
It is needless to say that the same effects can be obtained by implementing the same in equipment such as a freezer, a storage, and a showcase.

[0013]

In the air filter device of the present invention such as an ice maker, even if the air filter is not properly mounted on the rail attached to the lower surface of the main body, the air filter end portion is closed by closing the door. The air filter is securely attached to the regular position on the lower surface of the main body by pushing the upper protruding part of the main body against the lower end surface of the main body by being pushed by the door, so that the intake of cooling air formed on the lower surface of the main body is taken in. By completely covering the mouth from below with an air filter, it is possible to reliably and easily prevent dust, insects, and the like from entering the main body through the intake.
